Scanning Tunneling Microscopy at the Polymer-Metal Interface

The Scanning Tunneling Microscope (STM) will be discussed as a tool to investigate the polymer—metal interface on the one hand and to address individual organic molecules on the other hand. Examples will be given for two classes of systems: (i) Single polymer molecules on a conducting substrate (alkylated cellulose on graphite) and (ii) two organic conductors (a radical cation salt and doped polyacetylene) interfaced and imaged by the tip of the STM.
